Amine−Amide Equilibrium in Gold(III) Complexes and a Gold(III)−Gold(I) Aurophilic Bond

Inorganic Chemistry, 2007
The ligands HN(CH2-2-C5H4N)2, BPMA, and PhCH2N(CH2-2-C5H4N)2, BBPMA, react with Na[AuCl4] to give the cationic complexes [AuCl(BPMA-H)]+ and [AuCl(BBPMA)]2+, respectively. The amido complex [AuCl(BPMA-H)]+ undergoes easy inversion at the amido nitrogen atom and can be reversibly protonated by triflic acid to give [AuCl(BPMA)]2+. The complex [AuCl(BBPMA)

Dual facet of gold(iii) in the reactions of gold(iii) and porphyrins

Dalton Transactions, 2012
We have firstly demonstrated the dual facet of gold(III) in the reaction between gold(III) and porphyrins, which could be tuned through changing the counter ions, ligands and the electronic effect of the substituents of the porphyrins.

Reductive carbonylation of gold(III) chloride

Journal of the Chemical Society, Dalton Transactions, 1976
The reaction of anhydrous AuCl3 with CO in thionyl chloride gives [Au(CO)Cl] in substantially quantitative yields. The reaction takes place via the intermediate formation of a soluble carbonyl species which has been characterised spectroscopically and is believed to be a mixed-valence carbonyl complex of formula [Au2(CO)Cl4].

A Nucleophilic Gold(III) Carbene Complex

Angewandte Chemie International Edition, 2017
AbstractThe first AuIII carbene complex was prepared by reacting a geminal dianion with a (P,C) cyclometalated AuIII precursor. Its structure and bonding situation have been thoroughly investigated by experimental and computational means. The presence of a high‐energy highest occupied molecular orbital (HOMO) centered at the carbene center suggests ...

Triplet Photophysics of Gold(III) Porphyrins

The Journal of Physical Chemistry A, 2005
Gold porphyrins are often used as electron-accepting chromophores in donor-acceptor complexes for the study of photoinduced electron transfer, and they can also be involved in triplet-triplet energy-transfer interactions with other chromophores. Since the lowest excited singlet state is very short-lived (240 fs), the triplet state is usually the ...

Theoretical chemistry of gold. II

Inorganica Chimica Acta, 2005
Gold is an element whose unique properties are strongly influenced by relativistic effects. A large body of appropriate calculations now exists and its main conclusions are summarized in this critical review. The present paper completes the recent reviews by Pyykkö (2004, 2005) (529 references).

Some gold(III) derivatives of pyrazoles

Inorganica Chimica Acta, 1985
Abstract Various gold(III) derivatives of pyrazoles, pzH, were obtained and characterized. Besides the salt [3,5-Ph2pzH2][AuCl4], they included adducts, AuCl3·pzH, μ-pyrazolato-N,N′-derivatives, [Cl2Au(pz)]n (such as: n = 2 and pz = 3,5-diphenyl-4-chloropyrazolato), and one derivative containing both a neutral pyrazole and a pyrazolato ligand, Cl2Au ...

Gold(III) Complexes in Medicinal Chemistry

Future Medicinal Chemistry, 2014
A number of gold(III) compounds has been designed with the objective of overcoming the disadvantages associated with the platinum-based drugs for cancer treatment. Compounds of a remarkable structural manifold show significant antiproliferative effects in vitro against a number of cancer cells, including cisplatin resistant ones.
